ROBERT F. JUNGNIGKEL, OF MINNEAPQLIS, MINNESOTA.

MACHINE FOR APPLYING CROWNS T0 BOTTLES.

Application filed. November 28, 1913.

To all whom it may concern Be it known that 1, ROBERT F. JUNG- NICKEL, acitizen of the United States, residing at Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in Machines for Applying Crowns to Bottles; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to machines for applying metallic stoppers orso-called crowns to bottles, and has for its object to provide anextremely simple and highly efficient device for accurately positioningthe crowns in the operation of applying the same to the bottles. I

Particularly, this invention relates to automatic crown machines of thekind wherein the metallic bottle crowns are automatically fed from ahopper through a supply chute, to so-called crowning heads that aremounted on a rotary bottle carrying cage.

My invention provides a positioning arm or spring which serves toaccurately position the bottle crowns in alinement with clenchingrecesses provided in the crowning heads for the reception of the crownsand necks of the bottles, in the act of applying the crowns to thebottles.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation withsome parts broken away and with some parts sectioned, showing portionsof an automatic crown machine of the type above referred to, having myinvention applied thereto; Fig. 2 is a diagrammatic plan view with someparts broken away showing parts of the machine found in the vicinity ofthe line marked 00 00 on Fig. 1; Fig. 3 is a section taken approximatelyon the line x m on Fig. 1 and showing the parts on an enlarged scale;and Fig. 4: is a section taken on the line w 00 on Fig. 3.

Of the parts of the automatic crowning machine, it is only desirable forthe purposes of this case to briefly note the following elements,to-wit, the numeral 1 indicates a fixed upright column around which aheavy column sleeve 2 is arranged to rotate, with its lower end listabove a fixed cam plate 3 hav Specification of Letters Patent.

ing raised plunger actuating cam surfaces 4. The sleeve 2 carriesplunger guiding disks 5 and 6 and an upper disk 7. This upper disk 7carries upright circumferentially spaced crowning heads 8 having axialbores that extend downward through the said disk 7. The disk 7 isprovided with a peripheral groove that leads to the bores of the severalcrowning heads 8. Within the crowning heads are clenching devices, notshown.

The crowns indicated by the character y are placed in the hopper securedon the upper end of the column 1. In Fig. 1, the base 9 only of thishopper is shown. The crowns are fed from the hopper through a crownchute 10, the lower end of which terminates within the peripheralchannel 7 of the disk 7 so that under rotation of the said disk, thecrowns will be delivered one after another into the lower extremities 11of the bores of the crowning heads. As shown in Figs. 2, 3 and 4, theselower extremities 11 of the bores of the crowning heads 8, open into thesaid peripheral channel 7*.

The sleeve 2 and disks 5, 6 and 7 consti tute what in the trade has beendesignated as the cage of the machine. The heads 5 and 6 have verticallymovable plungers 12 axially alined with the crowning heads 8 and adaptedto support the bottles 2 on their upper ends. The lower ends of the saidplungers rest on the cam plate 3, and, at the proper time, are passedover the cam 4: and the said cam thus operated in succession to raisethe bottles and force the necks against the alined crown and up into theoverlying crowning head 8.

This much of the construction and operation of the machine is well knownto all persons familiar with the operation of bottling machine of theso-called automatic crowning machine type. In the operation of thesemachines, it was found that bottles will be frequently broken simplybecause the crowns g which were forced into the open lower ends 11 ofthe crowning heads, would jar or rattle slightly out of axial alinementtherewith. This I prevent by the use of a spring arm, against which theouter edges of the crowns will be pressed, at the time the bottle isforced upward into the crowning head. This spring arm lightly pressesthe crown into the open lower end 11 of the crowning head at such timeand keeps the same in true axial alinement both with the bottle and Withthe crowning head. Preferably, this spring positioning arm is in theform of a leaf spring 13 secured to a metal bar 14, which, in turn, issecured to a post. 15 on a fixed table 16 that surrounds the disk 6.

As already indicated, the improved crown alining device preventsbreaking of bottles. In running machines of this kind, the fingers of agood many operators have been crushed or cut off in an attempt toproperly ahne the crowns at the. time the bottles are moved upward toforce the crowns into the crowning heads. My automatic ali'ni'rigdevice, as is obvious, entirely removes the cause for such accidents.

heefiicien'v of cct wn p s tio ng evice described has been demonstrated,in practice, and hasbeetli mll dthat, by the use ereof, b ea'k 9 b s duga ad annement bit the crowns, is done away'with.

What I claim is: j

In a mach ne or app y g crew to bottles, the combination with a rotarycaria ertic ly n bve bet l fsl pi or s p u s r an l ip ra n cr wn n heas; n s id ar ia e Sai r wn n 'h a s being providedwithmeans for rebivingthe crowns of a yielding crown-positioning arm bottles into saidcrowning heads, a crown delivery chute for delivering crowns to saidcrowningv heads in succession, and a relatively fixed spring armarranged to engage the projecting edges of the crowns in succession andat the same time that the corresponding plungers are raised to force thenecks of the bottles against said crowns and" into said crowning heads.

In testlmony whereof I affix my signature in presence of two w tnesses.
